INTRODUCTION

Young people are the future of the country and the hope of the nation. Their physical health is directly related to the future development of China and the prosperity and decline of the nation. The results show that compared with the health level before 2010, the obesity detection rate continues to increase; the national physical fitness continues to show a slow decline; the health compliance rate of people at all stages is still high, and the detection rate of many people has a significant increase in poor health. The survey results Very worrying. Why does the survey result deviate from the attention and emphasis on human sports life in peacetime? Therefore, it is particularly necessary for us to investigate and analyze the implementation and implementation effects of sports documents, rules and regulations and opinions related to the human body, to find out the existing problems, and to propose improved countermeasures against the problems. Here is a study on the effect of physical exercise-related sports. The paper analyzes the influencing factors of physical exercise-related sports in order to find the existing problems and propose corresponding countermeasures to provide practical and theoretical basis for the implementation of healthy sports documents, rules and regulations and opinions for human health. Effectively promote the development of physical and mental health.¹

METHOD

Object

This paper randomly selects ten cities, and randomly selects 120 people from each city as the research object. Through literature method, questionnaire survey method, interview method and mathematical statistics method, the effect of carrying out physical exercise related sports is researched.

STATISTICAL METHODS

Partial normal distribution

In 1985, Azzalini first researched and proposed a partial normal distribution. If the random variable Y obeys the partial normal distribution, that is, $Y\sim SN\left(\mu ,{\sigma }^2,\lambda \right)$ , where µ represents the position parameter, σ represents the scale parameter, and λ represents the skewness parameter, then its probability density function can be expressed.²

$f(y)=\frac{2}{\sigma }\left(\frac{y-\mu }{\sigma }\right)\mathrm{\Phi }\left(\lambda \frac{y-\mu }{\sigma }\right)$ (1)

Where $\phi (\cdot ),\mathrm{\Phi }(\cdot )$ is the density function and distribution function of the standard normal distribution, respectively. When the skewness parameter λ=0, the formula (1) degenerates to the normal distribution density function, that is, the partial normal distribution degenerates to the normal distribution at this time. Figure 1 shows the image of the standard normal distribution.³ The mean and variance of the partial normal distribution are

Figure 1
Image of standard normal distribution.

$\mathrm{Mean}(Y)=E(Y)=\mu +{\mu }_0(\lambda )\sigma ,\mathrm{Var}(Y)={\sigma }_0^2(\lambda ){\sigma }^2$ (2)

Among them

${\mu }_0(\lambda )◻\sqrt{\frac{2}{\pi }}\frac{\lambda }{\sqrt{1+{\lambda }^2}},{\sigma }_0^2(\lambda )◻1-\frac{2{\hat{h}}^2}{\pi \left(1+{\lambda }^2\right)}$ (3)

The partial standard mode regression model

Mode is the most frequent sign value in the population. It describes most levels of the central tendency of the overall data. In skewed data analysis, the model is more widely used than the mean.⁴ According to Azzalini, the model under the partial normal distribution can be obtained. The expression is

$\mathrm{Mode}(Y)=\mu +m_0(\lambda )\sigma$ (4)

Among them

$m_0(\lambda )\approx {\mu }_0(\lambda )=\frac{t_0(\lambda ){\sigma }_0(\lambda )}{2}-\frac{\mathrm{sgn}(\lambda )}{2}\exp \left(-\frac{2\pi }{|\lambda |}\right),t_0(\lambda )◻\frac{4-\pi }{2}\frac{{\mu }_0^3(\lambda )}{{\sigma }_0^3(\lambda )}$ (5)

This article establishes the mode regression model under partial standard data as:

$\left\{\begin{array}{l}{y}_i\mathrm{ind}SN\left({\mu }_i,{\sigma }^2,\lambda \right),\\ \mathrm{Mode}\left(y_i\right)=x_i\beta \\ {\mu }_i=x_i\beta -m_0(\lambda )\sigma ,\\ i=1,\cdots ,n\end{array}\right.$ (6)

Where Y_i is the explained variable, subject to a partial normal distribution with position parameter µ, scale parameter σ, and skewness parameter λ. $x_i=\left(x_{i1},x_{i2},\cdots ,x_{ip}\right)$ is an explanatory variable with 1×p dimension, and $\beta ={\left({\beta }_1,{\beta }_2,\cdots ,{\beta }_p\right)}^T$ is a mode with dimension p×1 unknown parameters of the regression model.⁵ Now given a set of observation data $\left(y_i,x_i\right),i=1,\cdots ,n,y_i$ as random variables that independently obey a partial normal distribution, the linear regression model of equation (2) can be expressed as:

$y_i=f\left(x_i,\beta \right)+{\epsilon }_i,i=1,\cdots ,n$ (7)

Where $f\left(x_i,\beta \right)={\mu }_i+m_0(\lambda )\sigma =x_i$ ,β is the linear function of the parameter β, and $\beta ={\left({\beta }_1,{\beta }_2,\cdots ,{\beta }_p\right)}^T$ is the coefficient vector of the regression equation. $\epsilon ={\left({\epsilon }_1,{\epsilon }_2,\cdots ,{\epsilon }_n\right)}^T$ is the random error and obeys ${\epsilon }_i◻\mathrm{SN}\left(-m_0(\lambda )\sigma ,{\sigma }^2,\lambda \right)$, $x_i=\left(1,x_{i1},\cdots ,x_{ip}\right)$, Note that $X={\left(x_1,x_2,\cdots ,x_n\right)}^T$ is the design matrix of n×p dimension and rank p, then the vector form of equation (3) is given

$y=f(X,\beta )+\epsilon$ (8)

RESULTS

Questionnaire survey

INVESTIGATION RESULTS AND ANALYSIS OF INFLUENCING FACTORS

Investigation results and analysis of reasons why high school students do not participate in sports activities

When answering the questionnaire question “The main reason why you are unwilling to participate in sports activities (single choice)”, the factors from high to low selection are, in order, the time required for learning and lack of exercise, and the impact of the sports environment (including sports coaches, friends, and sports regulations). System, compliance, etc.), family sports environmental impact (including family members and living environment, etc.), lack or lack of venues and facilities, no guidance or no one to participate in activities,⁷ not interested in sports, no special reasons, people's sports environmental impact, The result is shown in Figure 2 .

Figure 2
A list of reasons why people do not participate in sports activities.

From the data in the figure, it can be seen that the main reasons for reluctance to participate in sports activities are heavy learning and work, physical exercise environment, family environment, lack or absence of venues and equipment; people’s environment has little impact on sports activities.

Investigation results and analysis of reasons for high school students to participate in sports activities

When answering the questionnaire question “What motivates you to do physical exercises (single choice)”, the factors in descending order of the number of choices are the fun that physical activities bring to you, the improvement of physical fitness, and the impact of the physical environment (including teachers, classmates and Sports regulations, compliance, etc.), family sports environmental impact (including family members and living environment, etc.), media influence, sports celebrity influence, relatives and friends acquaintance influence, other reasons, people’s sports environment influence, the results are shown in Figure 3 .

Figure 3
List of reasons to encourage people to participate in sports activities.

From the data in the figure, it can be seen that the main reasons for promoting physical exercise are the fun that physical activities bring to oneself, the improvement of physical fitness, the sports environment, and the family sports environment; among the reasons for promoting participation in sports activities⁸

INVESTIGATION RESULTS AND ANALYSIS OF THE STATUS QUO OF THE INFLUENCE OF FAMILIES ON HIGH SCHOOL STUDENTS’ SPORTS BEHAVIORS

influence of families on sports behaviors

When answering the questionnaire question “Family factors that affect your participation in sports activities (multiple choices)”, the factors that choose from high to low are people’s attitude towards sports, people’s habits of physical exercise, people’s education level, and family sports consumption Status, other, and no family factors, the results are shown in Figure 4 .

Figure 4
Summary of the influence of family on people's sports behavior.

From the data in the figure, it can be seen that people's attitudes towards sports and people's physical exercise habits have a greater impact on sports behavior, which shows that people's support and encouragement of sports and people's role in leading by example have a positive impact on people's sports behavior.

Investigation results and analysis of the status quo of the impact of schools on high school students’ sports behaviors

When answering the questionnaire question “Factors that affect your health in participating in sports activities (multiple choices)”, the factors that choose from high to low are obesity pressure, healthy sports atmosphere, outdoor sports activities, venue equipment, and healthy The results of sports competitions, teaching, and others are shown in Figure 5 .

Figure 5
An overview of the impact of schools and other sports grounds on people's sports behaviors.

This shows that the pressure of obesity restricts the body’s enthusiasm for physical activities; healthy sports atmosphere and outdoor sports activities also fail to promote the body’s physical activities.

Investigation results and analysis of the status quo of the impact of society (community) on high school students' sports behaviors

When answering the questionnaire question “Social (people) factors that affect your participation in sports activities (multiple choices)”, the survey results are shown in Figure 6 .

Figure 6
Overview of the impact of schools on people's sports behaviors

The most popular choice is no people’s influence. The number of people is 356, accounting for 31.2% of the total, which shows that human factors have little influence on sports behavior.

DISCUSSION

Cause analysis

Through questionnaire surveys and interviews, it is learned that due to the influence of traditional concepts, physical health plays an important role in the family, health, and society. It is self-evident that sports life and sports activities are not guaranteed, and the body’s physique is worrying.

From the individual level of the human body, whether to insist on physical exercise is the dominant need of the human body. Many people due to lazy thinking, determine the health and destiny of the human body to a certain extent. Other needs including physical activities are Less affected by the dominant need of thought. When sports activities conflict with lazy ideas, they often choose to be lazy instead of participating in physical exercises, reduce physical activities or give up physical activities. This is the physical exercise obtained from the investigation and analysis. The main reason for the poor development of related sports.

Related countermeasures

The country should consider the combination of sports and obesity systems, improve the obesity system, and still have a truly effective and relaxed living environment for sports. Two methods can be considered. One method is to conduct a national sports test, and the results of the sports test should be linked to many aspects, to enhance the enthusiasm of physical exercise and promote physical and mental health.

The state and educational administrative departments at all levels and health departments must implement and implement sports policies, rules and regulations, and document requirements, regard human physical and mental health as a major event related to the prosperity of the country and the prosperity and decline of the nation, and implement a full-time leadership responsibility system and The democratic supervision system puts the physical exercise of the human body in place and promotes the healthy growth of the human body.

Implement a democratic supervision system: The Ministry of Education, the State Sports General Administration and the Central Committee of the Communist Youth League jointly set up a national body sports supervision agency and formulate supervision rules. Supervising agencies should carry out their work independently, do not practice favoritism, conduct irregular visits and on-site investigations to different regions and different health, and can also conduct home visits or telephone interviews to understand the facts of people’s implementation of sports policies and documents, and they are targeted. The improvement of the work to effectively promote the healthy development of people's body and mind.

CONCLUSION

Through questionnaire surveys and interviews, it is learned that due to the influence of traditional concepts, the status of healthy physical exercise in the family and society is self-evident. Worrying. People need to start from many aspects to strengthen physical exercise of the human body and improve physical fitness.
